malloc用法:malloc函数详解。在CUDA中可以使用cudaMallocHost函数代替malloc,Since
the memory can be accessed directly by the device, it can be read or written with much higher bandwidth than pageable memory obtained with functions such as malloc(). Allocating excessive amounts of pinned memory
may
degrade system performance, since it reduces the amount of memory available to the system for paging. As a result, this function is best used sparingly to allocate staging areas for data exchange between host and device,分配Host变量空间是cudaMallocHost函数最佳使用阶段。
vim自定义注释快捷键:vim里如何快速注释一行
vim Normal模式(命令模式)下:gg到文件头,G到文件尾
详解CUDA核函数及运行时参数<<<>>>:核函数只能在主机端调用,调用时必须申明执行参数。调用形式如下,详见解释。<<<>>>运算符对kernel函数完整的执行配置参数形式是<<<Dg,
Db, Ns, S>>>
